VALVED HOSE-CONNECTING CONIDUIT.

a specification.

My present invention pertains to couplings for hose, pipes and the like.

The object of the invention is to provide a coupling designed more especially, though not necessarily, for use in connection with the sprinkling hose of a locomotive, the said hose being designed to throw hot water un-.

der pressure against a locomotive for cleaning purposes, and the coupling being constructed with a view of automatically cutting off the hot water, steam, 'etc., in the event of the hose being blown ofl the coupling, as frequently happens because of the high pressure.

By effecting the closure of the passage through the coupling coincident with the displacement of the hose from the coupling, the coupling may be depended onto prevent the discharge of scalding water on the attendantusing the hose, or upon any other person.

With the foregoing in mind, the invention will be fully understood from the following description and claims, when the same are read in connection with the drawings, accompanying and forming part of this specification, in which:

Figure 1 is a sectional view, with some of the parts in elevation, illustrating the coupling constituting the best practical embodiment of my invention that I have as yet devised. Fig. 2 is a transverse section taken in the plane indicated by the line 22 of Fig. 1, looking in the direction of the arrow, with the hose and the hose clamp omitted.

Similar numerals of reference designate corresponding parts in both views of the drawings:

The body 1 of my novel valved coupling is interiorly threaded at its inner end, as indicated by 2, to permit of the body being connected to a threaded cook or other appurtenance on a boiler or other source of water supply.

At an intermediate point of its length, the body 1 is provided with a chamber 3 to receive a ball valve 4, and in front of the Specification of Letters Patent. Patented Jan, 12, 1915- Application filed April as, 1914. Serial no. 834,990.

said chamber 3 the body is provided with avalve seat 5. v 1 j The portion of the body 1 that extends forwardly from the seat 5, is provided 'at 6 with "an exterior longitudinal groove,and formed in the wall of the said portion and communicating. with the said groove is a longitudinal slot 8. Disposed and adapted to be moved longitudinally in the groove 6 is a slide 9, having, by preference, an exterior protuberance 10. On its'inner side the slide '9 isprovided with a projection-11,.

which extends inwardly through and is movable in the slot 8. To the said projection 11 is fixed in any approved manner a pin 12 which is arrangedin the body of the coupling, and is designed under normal conditions to bear against the'ball valve i so as to hold the said'ball valve away from its seat and permit of the free passage of hot water through the couplingbody.

It will be observed by reference to the drawing that the body 1 is provided at an intermediate point of its length with a swell or rounded enlargement 10*, and that when the slide9 is in the position shownin Fig.

1, its protuberance 10 rests flush with said enlargement .10". g Secured by suitable clamping means as 13 around the coupling body 1 and the slide 9, is a hose 1 1, designed to be used to discharge hot water on a locomotive with a view to cleaning the same. When secured as stated on the coupling body 1 and the slide 9, the hose operates to retain the slide and the pin 12 in the relative positions illustrated, and consequently the pin holds the valve 4 away from its seat, so that no obstruction is offered to the passage of the hot water through the coupling. In the event, however, of the hose 1 1 being blown off the coupling body, the slide and the pin will be left free to move outwardly. From this it follows that coincident with the displacement of the hose, the head of Water will seat and close the valve, and consetuberance 10, there is no liability of the slide Working outwardly L inside l the hose.

This is an important advantage, sinceit precludes casual movement of the valve ltojts seat 5.

The construction illustrated and specifically described is the best embodiment of my inventionfof which I am cognizant but it is to be understood that in the future practice of my invention 'suchchanges in s ruc ure m y ade aso ai y f l W t in thescope of'my invention as defined in the sl imsappend I: a I,
